As a leader of a technical operations team I often have to work on technical operations engineer hiring. This process involves a lot of interviews with candidates and during those interviews along with many challenging practical questions I really love to ask questions like “What are the most important resources you think an Operations Engineer should follow?”, “What books in your opinion are must-read for a techops engineer?” or “Who are your personal heroes in IT community?”. Those questions often give me a lot of information about candidates, their experience, who they are looking up to in the community, what they are interested in, and if they are actively working on improving their professional level.

Recently, one of the candidates asked me to share my lists with him and I thought this information could be valuable to other people so I have decided to share it here on my blog.

Pluggable M3 (Monitis Monitor Manager) Framework

Who needs an introduction about M3? – Perhaps no one!
After gaining some reputation with M3, providing extra-easy integration of any monitor into Monitis it was time to take it to the next level.

Generally speaking, the work flow of M3 was described in detail in this article.

After some thought and design, we’ve decided it’d be best if M3 was pluggable. Pluggable in terms of being able to easily add execution and parsing plugins.
The interface and behavior of M3 …

Our Universe is full of ironies. But some ironies are just too hard to take.

As you may have guessed (!!!), I am an avid Linux developer and user. Though once upon a time I did develop under Windows. Yes, believe it. And on one particular case, I got to be on a first-name basis with some of the Microsoft Software Engineers to resolve issues we were having with their OLE crap — what the Holy Gods of Microsoft decided to redub as “Active-X”.

But I digress. For the past 10 years, I have been solid Linux and have defenestrated Windows for the most part. But as you know, you can never really completely eliminate Windows.  Despite your best efforts, it will always be (for now, at least) the 500 pound gorilla in any room you care to be in. The installed software base there is just staggering, and most have no Linux options.

But then that’s why projects like Wine and the many wonderful hypervisors …

If you are a GUI-oriented person, you need not read this. But if you are like me, you make heavy use of the console. If you are managing many machines as well as your own Linux workstation, it’s VERY important to know where your console session is.

Too many times in the past I had wanted to bring down my workstation, and would type “shutdown” or “reboot” in the console window, only to find out to my horrors that the console was really a remote session to one of my web servers serving up hundreds of web sites.

Whoops!

Well, that prompted me into developing a solution where I can tell at a glance where I happened to be logged in. This way,  I wouldn’t be in danger of issuing dangerous commands on the wrong server. And if you are working for someone else, it also keeps you from being FIRED!

I use KDE to do my development and …
